v Mw- 'I a',

AThe Schedule referred to in these Letters Pate-ritand making part of the sarna Be it known that I, HIRAM L. HWARD, of Mendon, in the county of St. Joseph and VState of Michigan, have invented a new and useful Improvement in Shears for Gutting Metallic Bolts; and I do declare that the following is a true and accurate description thereof, reference being` had to the accompanying drawings and 4to the letters of reference marked there on, and being a part of this specification. i

rlhe drawings represent my invention open and ready for use, with a section of an iron bolt inserted between the shear-blades; the red lines show the position of` the various parts when closed.

The nature of' this invention relates to the construction of an implement for cutting iron bolts and other metallic articles, and will be found especially adapted to the requirements of carriage-makers and blacksmiths in cutting ofi' bolts and other similar work; and

It consists in a pair of' jaws provided with suitablecutting edges, operated by a. series of compound levers, whereby an inunense power is fexerted upon the. jaws to compel them to easily perform the work for which they are designed.

In the drawings- A represents the jaws provided with suitable cutting edges, B. v

C isa standard or frame, which may be made in two pieces, each siiniiar to the other, one of each being placed ou either side of the jaws, to which they are pivoted by means of the bolts a.

lothe -rear ends of the curved prolongations of the -jaws are pivoted the solid linksf'b,'by means of the bolts'o. 'A v The opposite ends of the links' are in turn'.` pivoted to the ears- B by means of the bolts d. d f

These ears form a part of the leversv E, which, are pivoted to the standard C by means of the bolts e.

A section of the head of these levers vE is shown l in Aa detached tigure,by which it '-will be-jseen that their inner faces are semicircular, and provided with cogs, which engage with each other; that is,lthe'cogs upon each hea-d engage with the cogs upon the other, thereby compe-lling a like movement to eaclrjaw.

The whole is so arranged that 'when thelevers are extended, as in the drawing, the jaws are opened to receive the bolt to be operated upon. d

By compelling the levers toward. eachother the jaws are forced together, cutting anyk substance that may be interposed between them.

W'hat I claim as my invention, and desire-to secure b v Letters Patent, is-

The construction of an implement for the purpose described, wherein the jaws A, provided witl' cutting edges B, the standard or trarne C, the ears D, levers E, klinks and bolts a., c, and e, are arranged substantially as herein set t'orth.
